One of the most common communication buses in the world, and hence one that should be well understood by prospective engineers, is the I2C bus. With the help of I2C communication is supported with various slow, on- board peripheral devices that are accessed intermittently, while being extremely...
基于MCU的低功耗I2C总线控制器设计与实现 引言 随着半导体产业的不断发展,片上系统(System-on-Chip, SoC)技术得到了不断的提高,SoC技术的概念是将多个拥有特殊功能的集成电路在一块芯片上集成[1]。SoC设计的关键技术包括总线架构技术、IP核可复用技术、软硬件协同设计技术、低功耗技术及SoC验证技术等[2]。此外,...
ST25DV-I2C iOS CryptoDemo application (STSW-ST25iOS003) shows how to establish a secure transfer channel over NFC between an STM32 microcontroller and an iPhone. It uses the fast transfer mode (FTM) feature of the ST25DVI2C NFC tag. To run the demonstration an ST25DV-I2C-DISCO b...
28 www.cypress.com 文档编号: 001- 82514 版本*C 1 简介 内部集成电路(IIC 或 I2C)是由飞利浦半导体公司(现为 NXP)开发的常用芯片间串行通信标准.I2C 为集成电路提 供了一种在同一印刷电路板(PCB)上进行通信的简单方 法.I2C 由一个简单的物理层组成,仅需要两个引脚和极少 的外部组件.与 SPI 等通讯标准...
Due to the internal IO line configuration, it is not possible to communicate with standard I2C cardsusing only IO as SDA line.This document gives two hardware methods to solve this problem by separating the I/O input andoutput on the host side :- the first method uses IO_uC as output ...
